SUPERHEATER specification of Letters Patent'. v

To all 'whom t may colwem:

Be it known that I, JACQUES L. VAUGLAIN, a citizen of the -United States, residing in Philadelphia, Philadelphia county, State of Pennsylvania, have invented certain new and useful Improvements in Superheaters,

of whichA the fo-llowing is a specification,

referencebein had to the .accompanying drawings, whic 1 form a parthereof.

This invention relates to superheaters for locomotive ,and like boilers in which the superheater ,pipes are located in a group 1n a large fire-tube or flue on the boiler.

The objectof the invention isto facilitate the insertion and removal of the individual superheater pipes and in accordance with the invention the steam from the boiler is delivered to a steam dome, which is preferably auxiliary to the main dome and has in its bottom a tube sheet in which the ends of thesuperheater pipesturned up at substantially a right angle to their length, are

suitably secured. v `The pipes extend for-- r wardlythrough the iue intothe smoke-.box

. planes sov as to permit the bent pipes to beI vintroducedvbetween them from the forward end and secured in the headers.

The invention will be more fully explained i where they are secured in the' usuall manner inl vertical headers separated in vertical hereinafter vwith reference to the accompanying drawings in which it lis illustrated and in which-v Figure 1 is a view partly in longitudinal, vertical section, showing so much of a steam boiler of ordinary type as is necessary to venable the application of the invention.

thereto to be understood. Fig. 2 is a view of the same in front elevation but onl a somewhat larger scale. Fig. 3 is a view vsimilar -to Fig. 2 but showing a slightly different` construction of the header. Fig. 4 is a detail view, on a larger scale than that of Figs. 2 and 3, showingl the preferred form of the joint in the steam pipe between the main.

--arrangement shown the main steam dome d is connected by asteam pipe h, having a telescoping, packed joint h', as shown in detail in Fig. 4, with an auxiliary steam dome e' which is suitably supported within an internal .shell 7c secured atA its lowerend to the large flue e, the latter being cut away -oiprovided with an opening as at e to permitvthe hot gases to. circulate arolmd the dome z' 'below the cap le of the casing k.' In the' Patented Apr. 1,1913. Application filed December 30, 1911. Serial No. 668,722.

bottom of the dome i is secured 'a tube sheet i. in which the, ends Z Vof the superheater pipes Z, bent upward at substantially right angles as showmare secured in any-suitable manner. The' superheater pipes-I are extended forwardly through the fine-'e and at j4 its forward end are secured',as usual,y in ,the-

rear face of headers m which are separated in vertical planesby spaces m which are suiiiciently wide to permit the superheater pipes to be inserted between` them. The spaces are also sufliciently high to permit the introduction of 'the pipes having the longest members l. As the tubes" are introduced in this manner they are properly secured at their rear, up 'er ends, to the tube sheet z" and att-heir orward. ends tothe rear face of the proper header. The several vertical headers or .header members m are secured to a cross header mzfwhich, as shownlin 2, may be at the lower ends of the vertical headers,` or, as shown Vin Fig. 3 may be at the upper ends thereof. ',Ihe delivery pipes n, by which the superheated steam is conducted to the cylinders, are connected to the cross vheader m2 in any -usual or suitable manner as shown invv Figs. 2 and 3'. I

It-will be observed that the superheater pipesmay b e introduced and removed readily and that their rear upper ends can be secured in the tube sheet 'when the cap 2 of the dome i is removedlwhile their forwardv ends are-secured in the headers mi in the usual 4manner. will be observed, is unidirectional. If. de# sired,a damper 0 may be located withn'the flue e and provided with a rod`0 by which it may be'raised or lowered and supported 'inan adjusted position. There is shown in the drawings o-ne flue e only, with a singlev group of superheater pipes. but it will be understood thatthere may be other fines, as l usual in boilers of this type, with or witho-ut superheater pipes. It will also be understood that the details of construction and arrangement may be varied in'otherpartcu-` The flow of the steam, it`r 25' steamat its upper end and having a tube 'sheety at its bottom,
